Bug#1010448: firmware-misc-nonfree: Please backport: nvidia: fix symlinks for tu104/tu106 acr unload firmware

Dear Maintainer,

Could you please backport this upstream fix:
f8462923ed8 "nvidia: fix symlinks for tu104/tu106 acr unload firmware"

I'm using nouveau with a GPU that uses the tu106 firmware. Before this
fix, suspend does not work (computer restarts immediately). After
changing the symlinks like this patch, it suspends successfully.
Resuming still doesn't work due to a separate problem.

Bug#1010458: linux/sysctl.h: unknown type name 'size_t'

I was cleaning up the example programs in the man-pages by using
iwyu(1), when I found that  is using 'size_t'
without including any definition for it.

See the following example program:

$ cat tmp/src/man2/sysctl.2.d/sysctl.c

#define _GNU_SOURCE
#include 
#include 
#include 
#include 
#include 
#include 

int _sysctl(struct __sysctl_args *args );

#define OSNAMESZ 100

int
main(void)
{
struct __sysctl_args args;
char osname[OSNAMESZ];
size_t osnamelth;
int name[] = { CTL_KERN, KERN_OSTYPE };

memset(&args, 0, sizeof(args));
args.name = name;
args.nlen = sizeof(name)/sizeof(name[0]);
args.oldval = osname;
args.oldlenp = &osnamelth;

osnamelth = sizeof(osname);

if (syscall(SYS__sysctl, &args) == -1) {
perror("_sysctl");
exit(EXIT_FAILURE);
}
printf("This machine is running %*s\n", (int) osnamelth, osname);
exit(EXIT_SUCCESS);
}

for which I get the following errors:

$ cc -c -std=gnu17 -Wall -Wextra -Werror -Wno-error=unused-parameter \
 -Wno-error=sign-compare -Wno-error=format \
 -o tmp/src/man2/sysctl.2.d/sysctl.o \
 tmp/src/man2/sysctl.2.d/sysctl.c;

It seems that it's supposed to know some types, but for some reason
'size_t' is not defined by the included headers:

$ grep include 
#include 


Cheers,

Alex
